The primer shall be suitable for spray or brush application. It shall have properties enabling it to penetrate through pores or cracks and fill them up, making the surface impervious. 13.8 Polymer based paints The materials used shall be high polymer based chloride and sulphide free cement and waterproofing additions and epoxy based waterproofing paints as per manufacturer's specification and approved by Engineer. 13.9 Fibre glass R. P. Tissue The fibre glass R.P. tissue is a thin flexible uniform mat, composed of glass fibre in an open porous structure bonded with a suitable inert material compatible with coal tar, asphaltic enamel and oil plastic based wall paint. The fibrous glass mat is reinforced with continuous filament glass yard at 3/8" (10mm) pitch in the longitudinal direction. PHYSICAL PROPERTIES i) Weight The average weight of fibre glass R.P. tissue shall not be less than 50 gms/sq.sm. ii) Thickness The fibre glass R.P. tissue shall have a thickness not less than 0.4mm. iii) Tear Strength The tear strength shall be not less than 900 grams in the transverse direction. iv) Breaking Strength This shall have a minimum breaking strength of 13 lb/in (2.32kg/cm) in the longitudinal direction. v) Porosity This shall have a porosity when related to pressure difference across the sample of not less than 0.022" (0.56mm) and not more than 0.76" (1.92mm) of water guage at an air velocity of 200fpm.(100cm/sec.). vi) Pliability There shall be no cracking of the tissue mat when bent over a 1/8" (3.2mm) radius after immersing for 10-15min. through a 90 degree arc. vii) Temperature The fibre glass tissue shall be Resistance under a load of hot bitumen at 530 degree F (276 degree C) for one minute. 13.9.1 Primer Primer shall conform to requirements laid down in IS : 3384-1986.
